Started in 1988, U.S. DataSource Corporation was the very first organization in the nation to collect, process and publish bank and government owned foreclosure lists to the public. Since inception, we have been publishing the most accurate and complete listings of bank-owned foreclosures (REO’s) and government-owned foreclosed property listings. Our proprietary data collection methodologies allow us to aggregate and publish foreclosure data from over 500 sources. We also sell trustee sale and sheriff sale data covering more than 2,000 counties.
